Offline Use of the Microsoft Dynamics CRM 2011 Services

Both Microsoft Dynamics CRM for Microsoft Office Outlook with Offline Access enables you to continue your work when you are disconnected from the server.

In addition, the event and plug-in infrastructure lets you leverage development investments across solutions by using the same APIs and programming model. The IOrganizationService methods and the Microsoft Dynamics CRM OData service methods function both online and offline. When using a method such as Create or Update offline, the data is written locally and then when the user connects to the server, the actions are played back to the server.

For more information about whether a message is supported offline, see Microsoft.Crm.Sdk.Messages. You can also determine whether a IOrganizationService message works offline by checking the SdkMessage.Availability attribute for the desired message. If the message works for multiple entity types, you must also check the SdkMessageFilter.Availability attribute to see whether the message is available offline for the entity you want to work with. For example, the Create message is available offline, but not for the queue, user, or site entities.
